Procedure to Clean Heavily Scaled
Ice Machines
Ice machines that are heavily scaled or have not been
cleaned on a regular basis will need to run this
procedure.
GENERAL
Clean and sanitize the ice machine every six months
for efficient operation. If the ice machine requires more
frequent cleaning and sanitizing, consult a qualified
service company to test the water quality and
recommend appropriate water treatment. The ice
machine must be taken apart for cleaning and
sanitizing.
CLEANING PROCEDURE
!
Caution
Use only Manitowoc approved Ice Machine
Cleaner and Sanitizer for this application
(Manitowoc Cleaner part number 9405463 and
Manitowoc Sanitizer part number 9405653). It is
a violation of Federal law to use these solutions in
a manner inconsistent with their labeling. Read
and understand all labels printed on bottles
before use.
!
Caution
Do not mix Cleaner and Sanitizer solutions
together. It is a violation of Federal law to use
these solutions in a manner inconsistent with
their labeling.
!
Warning
Wear rubber gloves and safety goggles (and/or
face shield) when handling ice machine Cleaner
or Sanitizer.
